VALVE-LIFTER.

Application led December 20, 1919. Serial No. 346,368.

To all /wzom z't may concern.'

Be it known that l, Lnoimnn il. EnronsoN, a citizen of the United States, and a resident of Dixon, in the county of L ee and State of illinois, have invented certain new and useful Improvements in Valve-Lifters, i

of which the following is a full, clear, and exact description.

The invention relates to valve lifters.

One object of the invention is to provide an improved lifter for use in connection with motors of automobiles or tractors and which is adapted to hold the valves in lifted position without removing the exhaust manifold which is usually disposed at the valve side of the motor. Another object of the invention is to provide an improved valve lifter.

lThe invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

ln the drawings: Figure l is a side elevation of the lifter showing the manner in which it is used. Fig. is e. perspective of the lifter-head.

The improved device comprises two members 4r and 5 which are pivotally connected by a pin 6 which extends through a lug 8 on member et and lugs 7 on member 5. These lugs are interi'itting so that the joint will serve to hold the members in alined relation. The outer portions of these members are of sui'licient length to serve as levers or handles. Member 4- is provided with an angular down turned portion S` whichy is pointed, as at 9, so that when itis placed on the flange on the crank-case or other portion of the motorcasing, it will not slip. Member 5 is pro-- vided with an upwardly extending' portion. l0 and a longitudinally extending fork ll which is formed with a slot l2 and adapted to straddle a valve-stein, and is recessed, as at 1.3, to receive the usual lock-nut or other projection on the stem. A locking bar 14 is pivoted to the member 5, as at l5, and is provided with ratchet-teeth 1G adapted to receive and interlock with the-outer end 17 of the member Il.

To use the device, the user will place .the point 9 of the member' 4 on the projecting portion of the crank-case such as the flange on the crank-case and to -slip the fork 1l of the member 5 under the spring-retaining nut or other projection on the stem of the valve, the slot l2 permitting this to be done.

The outer ends of the members 4 and 5 will y be spread apart before placing the fork in operative position. The user will then force the members together, and as this is done, the locking bar le will automatically lock the members together. The pressure from the spring of the valve against the member 5 will cause the point 9 of the lifter to iirmly engage the crank-case and thus the entire lifter will be held against displacement and the member 5 will hold the valve in lifted position for purposes understood in the art. T he point 9 is preferably hardened.

The invention is not to be understood as restrictedto the details set forth, since these may be modiiied within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described 'the invention, what l claimas new and desire to secure by Letters Patent, is:

l. A valve lifter comprising a pair of members pivotally connected together at a fixed point, one provided with downwardly extending means rigid therewith and adapted to engage a portion of the motor casing and the other with means to underlie and engage a part on the valve, both members extending outwardly from the pivot to serve as levers for operating their inner ends, said casing engaging means and valve part engaging means being out of vertical alinement so that the casing engaging means will engage the casing outwardly of the part on the valve.

valve lifter comprising a pair of members pivotally connected together at a fixed point, each having an outwardly eX- tending lever portion, one being provided with a downwardly extending point adapted to engage and secure the latter member againstlateral movement on a motor casing, the other with means for engaging a part on the valve.'

3. A valve-lifter comprising a pair of members pivotally connected together, each having an outwardly extending lever-por tion, one being provided with a downwardly extending point adapted to engage a motorcasing, the other with an upwardly extend ing portion and a laterally extending fork, a locking bar pivoted to the outer end of one of the members and provided with teeth formed to receive the outer end of the other member to lock the members together.
